If you have recently acquired an older property with a conservatory or your existing conservatory is showing signs of age, you might be curious about the cost of replacing it.

A fully fitted conservatory cost ranges from £6,000 to £20,000, including materials and complete installation, plus VAT. However, this price can vary depending on the size and style of the conservatory, the materials used, and any customisations. 

For instance, if you want to increase the conservatory’s size or change its style or materials, the cost may increase accordingly. Opting for a bespoke design can also cost more. You can also replace just the windows or roof, a cheaper option that ranges from £300 for windows to £4000 for roof replacements. 

There are four popular types of fully fitted conservatories: Victorian, Edwardian, Lean-To, and Gable. Each has unique features and benefits, and your chosen one will depend on your specific needs and preferences. 

For instance, Victorian conservatories are ornate and ideal for adding elegance to your home, while Edwardian conservatories are more modern and work well with contemporary homes. 

If you have limited space, a lean to conservatory is a great choice, while a Gable conservatory can create a grand and spacious feel. 

Considering the various conservatories and their pricing options, you can create a beautiful and functional space that meets your needs and exceeds your expectations.

Let's look at the prices for the most popular conservatory styles in the UK. 

The price of a replacement conservatory can differ depending on factors like the complexity of the design, the materials used, and any additional groundwork or structural work needed. 

You might save on the installation costs if you have a solid foundation. However, the foundation's condition must be assessed before any work can begin. LocalSurveyorDirect's article "Foundation Problem Under Conservatories" explains that shallow foundations in conservatories are at a higher risk of subsidence from seasonal ground fluctuations and nearby trees. 

Builders often use shallower foundations than Building Regulations allow when constructing conservatories; no knowledgeable person inspects them. 

According to Homeimprovementquotestoday, a conservatory roof replacement cost ranges between £4,000 and £20,000. However, it may not always be necessary to replace the entire conservatory. Updating the roof can make the conservatory look better and more usable. Replacing the roof can also make the conservatory more energy efficient, making it more practical and affordable.

Still, it heavily depends on the size of the structure and the roofing material chosen. 

Here's a look at the average costs based on the material and size:

Although polycarbonate is the cheapest choice, it may require greater maintenance or earlier replacement than sturdier materials such as glass or tiles. 

Weighing these considerations can help determine the upfront cost, and what’s best for your conservatory. 

According to construction company Fritta, based in London, the average cost of replacing a standard white uPVC casement window is £1,250. However, depending on the style, the company says you can expect to pay between £400 and £4,000 per window.

Faulty and outdated conservatory windows not only hinder proper airflow but also pose difficulties in operation, diminishing the aesthetic appeal of your conservatory. 

Upgrading the windows can work wonders if you want to give your conservatory a fresh and improved appearance. Your style and budget will determine the specific windows you opt for. 

The expense of replacing conservatory windows is determined by factors such as the type of glass, the size, and whether the window frames also need to be replaced. 

Below are the average costs based on the type of window and frame material:

It is important to consider your taste and budget when looking to replace your conservatory window frames. According to SRJWindows UK, uPVC frames are the most affordable and durable option on the market. 

These frames require minimal maintenance and do not need constant repainting like traditional wooden frames. They are highly resistant to warping, rotting or discolouration, making them a cost-effective and long-lasting investment in your home. 

uPVC frames also provide excellent insulation, keeping your home at a comfortable temperature all year round while saving you money on energy bills.

Whether you imagine transforming your conservatory completely or simply upgrading certain parts while keeping the existing structure, understanding the cost involved is crucial. 

Fortunately, budgeting doesn't have to be a burden, especially when you work with the right tradespeople who can guide you through the process.
